SPECIFICA TIGN forming part of Letters Patent N o. 602,310, dated April 12, 1398. Application led December 20, 1897. Serial No. 662,619. (No model.) Patented in England October 19,1893,No. 19,6 82.

To @ZZ whom. it may concern:

Be it known that I, BRAMAH JOSEPH DIP- LOOK, engineer, a subject ofthe Queen of Great Britain, residing at 53 Ashley Gardens, Westminster, London, in the county of Middlesex, England, have invented certain new and usefullmprovements in Locomotives, (for which I have obtained Letters Patent in Great Britain, No. 19,682, dated October 19, 11893,) of which the following is a specification.

This invention relates to locomotives mounted on springs, whether intended for running on rails or on roads, but more particularly to the latter; and it has for its object arrangements whereby both pairs of wheels can be driven and also turned for going around curves or steering, as the case maybe. For this purpose each pair of wheels is mounted on a swiveling undercarriage, and their axles are connected by universal joints to central wheels driven by a lost-motion pinion or pinions or the like on a shaft or shafts at the same level, or nearly so, with the axles, so that the distance between the axles and the shafts is substantially constant, although the engine rises and falls on its springs.

The drawings show a road-locomotive con-v structed according to this invention.

Figure l is a diagram side elevation showing the central gearing. Fig. 2 is a vertical section on either of the lines 2 2, Fig. 1the two undercarriages being identical the one to the other. Fig. 3 is a horizontal section on the line 3 3,l Fig. l. Fig. 4. is a part longitudinal central section on the lines 4. 4, Figs. 2 and 3. Fig. 5 is a detached side elevation of one of the drums with its springs. Fig. 6 is a part horizontal central section showing a modification.

In Fig. l, ct is a pinion on the crank or driving shaft, gearing with the wheel a', to which a pinion a2 is fixed. The pinion CL2 gears with the two lost-motion pinions 0.3, each of which gears with a ring of teeth d4 on the wheels b, Figs. 2 and 3. There may be only one lostmotion pinion of, but not so conveniently, or the lost-motion pinion or pinions instead of gearing directly with the teeth a4 may do so by means of chains or otherwise. Each wheel b is spherical inside and tits upon a spherical wheel c, Figs. 2 and 3, whose hub is free to turn on the through-axle d. The inside of the wheel b is slotted at b with parallel-sided horizontal slots to receive the square or oblong nuts or heads c', tree to turn on radial-spindles c2, fixed in the wheel c and projecting outward beyond the latter, or the heads c might be fixed to the spindles c2, the latter being free to turn.

e, Figs. 3 and 4., are beveled pinions free to turn on the spindles c2 and gearing with the beveled pinions f', fixed to the sleeves f2, forming the axles of the road or carrying wheels f. The beveled pinions form the ordinary compensating gear and may be omitted, but not advantageously. The sleeves f2 work in bearings oraxle-boxes g, which are rectangular on the outside and free to work up and down between horn-plates h', forming part of the vertical drum h, Fig. 5, which serves as a swiveling undercarriage. The

bearings g have downward extensions g, Fig.

2, pivoted by pins g2 to the levers j, Figs. 2, 3, and 5. The ends of the levers j support springs j and j?, Fig. 5. Caps h2, forming part of the drum h, rest on the tops of the springs j', and caps h3, connected by rods h4 to the ends of the lever h5, pivoted at h6, Fig. 3, to the drum h, rest on thetops'of the springs jg. The whole weight therefore of the drums h and the parts carried by them is supported by the springs j and j? Excessive sideway play of the bearings g in the horn-plates h is prevented by buffers bearing against the side faces of the hornplates. These buffers consist of pairs of vertical plates k and k', one pair of plates being on each side of each bearing g. The plates la are mounted on trunnions g3, fixed to the bearings g, and are held against the flat side of the latter by caps or nuts g4. The plates lo overhang the plates la at the top and bot# tom or may be connected thereto by dowels or the like. Springs k2 normally keep the vertical faces of the plates k and k a small distance apart and serve to lessen shocks, while also allowing the axle to tilt diagonally to the horn-plates when a sudden jolt of one wheel compresses the carrying-springs j' jz more on one side than on the other.

The surfaces of the plates la and la may be in contact with each other, the springs k2, the trunnions g3, the caps g4, and the overhanging ends of the plates k being all dispensed IOO with, the plate 7a being fixed to the bearing g and 7a' loose. In this case the surfaces between 7c and 7c must be curved to a radius struck from point 9c, Fig. 2, so that the curved inner surfaces of the plates 7c, sliding on the curved outer surfaces of 7c', can come nearer to the horn-plates when the engine tilts to compensate for the axle being diagonal to the horn-plates.

The loose platesl 7e are kept in place vertically by the curved surfaces, as described, and horizontally by any suitable form of guide or guides or other connections.

The drums 72, carry trunnions 707, Workin g in bearings Z' in the frame Z of the engine.

The weight of the engine-body and boiler is carried by live rings or rollers m, fitting loosely outside the bosses of the trunnions. The engine is steered by the hand-wheel n, Fig. l, actuating, by means of beveled gear, the shaft o, carrying right and left hand worms o', gearing with short Worm-segments p, Fig. 2, fixed on the tops of the drums 7L.

q, Fig. 2, are guides pivoted in the top and bottom of the drum 7L and serve to prevent the wheel l? from turning in a transverse plane. Preferably three guides are employed, the third, r, bein ghorizontal and fixed to the frame Zand carrying rollers 1" at its end, as shown in Fig. G.

lf the locomotive be intended for running on rails, the steering-gear is omitted and each undercarriage is provided with two pairs of wheels.
